For me, one of my most ''fun'' moments was when playing at a cities, and I got paired against a friend. I played Steelix Prime, he went for Lanturn prime (we both agreed to go rogue that CC). I open Chansey (Plt), a DCE, an Expert belt, and 4 Fighting energy =/ I top deck a pokémon communication as my first card. He opens a lone lanturn. Since he goes first, and the old rules apply (no trainers first turn, etc), he can't do anything except for attach one Electric energy, and hits me for 10. I look at my cards, and suddenly realises Chansey can hit 40 for a DCE. I attach the expert belt, and ''Chansey-Donk'' his lone Chinchou.
The term ''Chansey Donk'' is a real meme within my friend group since that day, and my friend actually complemented me on pulling it off...! xD
